I know your works. Behold, I have given before you an open door, which no one is inherently able to shut it, because you have little inherent ability and are in a state of guarding My Words and have not denied My Name (Revelation 3:8).
The Philadelphia assembly is characterized by its small size but strong adherence to God’s word. This assembly is understood to represent the condition of the Church on earth from approximately 1750 AD to 1906 AD. It is distinguished by its commitment to guarding God’s Word and not denying His name. As a result, it was granted an open door that no one could close. Through the efforts of this assembly, numerous regions worldwide experienced positive transformation. During this period, Bible translations expanded into many languages previously without access to the Scriptures. The assembly also established schools and hospitals. Furthermore, the conduct of its members contributed to significant social reforms, including the abolishment of slavery, the advancement of women’s education, and the development of Sunday schools to enhance children’s understanding of the Scriptures.
Members of the Sardis assembly, associated with Reformed Theology, who oppose the Philadelphia assembly and claim to be Jews, are described as belonging to the synagogue of Satan (Revelation 3:9). Satan sends his followers into assemblies belonging to God to imitate Christians. These individuals present themselves as ministers of righteousness (2 Corinthians 11:15). They are identified as teachers who distort the grace of God into licentiousness, promote material wealth over godliness, advocate works over grace as the means to righteousness, reject the proper order of the Church, and mislead the uninformed (Jude 4, 11; 1 Timothy 6:5; 2 Corinthians 11:20). Although they do not outwardly appear wicked, they present themselves as devout individuals who follow God, maintaining a form of godliness while denying its inherent power (2 Timothy 3:1–5).
The Philadelphia assembly continues to possess an open door, despite its small size. Its members remain committed to upholding God’s Word, diligently guarding its teachings and conveying the truth. In identifying such assemblies in the contemporary context, certain characteristics are evident: they adhere to the gospel for salvation without additions (1 Corinthians 15:3–4), maintain apostolic teachings regarding victory over sin (Romans 6:4–6, 11, 13), stand firm against Satan (Ephesians 6:10–18), and overcome the world system (1 Corinthians 7:31; 1 John 2:15). These assemblies also teach about the new creation, with Christ as the head and the Church as the body (2 Corinthians 5:17; Ephesians 2:21–22). Furthermore, they are distinguished by their accurate interpretation of the word of God, based on the revealed seven dispensations (Ephesians 1:10; 3:2; Hebrews 3:5; 2 Timothy 2:15).
This assembly is comprised of believers who will all be saved from the coming wrath (Revelation 3:10). In contrast, unbelievers within the assemblies of Thyatira (identified with Catholicism and its derivatives), Sardis (Reformed Theology), who are described as having a name but being spiritually dead, and Laodicea (Progressive Christianity), characterized as lukewarm, will be cast into the Tribulation Period. No Christians will be left behind, only those whom Christ does not know (1 Thessalonians 5:9).
